What problem does it solve? Reviewing a branch or PR requires checking two independent things at once: whether the code follows the repo's documented standards and whether it actually implements what the issue or spec asked for. Doing both in one pass lets one concern mask the other, and doing it manually is slow and inconsistent. ## Core Features & Use Cases - Two-axis review: Runs a Standards review (documented repo standards plus a fixed Fowler code-smell baseline) and a Spec review (requirements coverage, scope creep, wrong implementations) as parallel sub-agents, then reports them side by side without merging or reranking. - Fixed-point diffing: Pins any commit, branch, tag, or merge-base the user supplies, validates the ref and non-empty diff before spawning reviewers, and uses three-dot git diff semantics. - Automatic spec discovery: Locates the originating spec from issue references in commit messages, a user-supplied path, or spec files under docs/, specs/, or .scratch/. - Use Case: Before merging a feature branch, ask for a review since main and receive a ## Standards report citing violated conventions and smells, plus a ## Spec report quoting unmet or over-built requirements. ## Quick Start Ask the assistant to review the changes on this branch since main using the code-review skill.
